CarrollTouch Technology Specifications

Construction

The CarrollTouch IR XRES frame is a solid state circuit card assembly.
The circuits are populated onto .062" thick FR4 printed wiring board
material with a UL flammability rating of 94V-0. The IR transparent insert
attached to the circuit card assembly is polycarbonate material with
a UL flammability rating of 94V-0 at thicknesses of .090 inches and above,
and 94V-2 at thicknesses from .034-.089 inches.

The cable exits from the left center of the frame assembly and is a
16 position, 0.5 mm flat flex cable (FFC). The cable terminates into
a ZIF connector on both sides of the controller and frame interface.

The FFC cable can be folded and creased. Test data for this cable reveals
that the cable maintains electrical characteristics over 20 million cycles
of a simulated forming bend around cylinders of radius 0.5", 0.75",
and 1.0". The FFC is guaranteed to maintain electrical and plating
characteristics for a minimum of 25 insertion and withdrawal cycles with
the ZIF connector.

Replacement cables: P/N A47654-000

Positional Accuracy

The positional accuracy of the IR XRES frame to a touch stylus is a
function of the physical spacing of the discrete IR opto-electronics,
diameter of the touch stylus, and location of the stylus in the touch
active area.

1 Typical accuracy demonstrated by product using a stylus
greater than minimum specified diameter. See note 4. 2 Minimum accuracy demonstrated by product using a stylus
greater than minimum specified diameter. See note 4.3 Percent of touch area that may possibly exhibit the minimum
accuracy parameter. See note 4.4 Minimum stylus diameter required for a touch response.

Touchpoint Density

Touchpoint density is based on controller resolution of 4096 x 4096.
This equates to more than 100,000 touchpoints/in2 (15,500
touchpoints/cm2) for a typical touchscreen used with Elo TouchSystems
controllers

Thermal Cycling

The touch system shall be capable of functioning normally after the
completion of 50 thermal cycles from room conditions to +85ºC to
-40ºC and then back to room temperature at a rate not to exceed
2ºC per minute with a one hour soak at each temperature extreme.

Ambient Light

The IR touch screen shall be capable of operating in the following
ambient light conditions when mounted in a typical application enclosure:
